The incident happened on Thursday outside the Macy's in Manhattan, where Justin, 17, was promoting his new fragrance Someday.

Police said Justin's representatives contacted them to say he wanted to go outside to greet fans. Police set up a small pen where he could do so.

Justin then left the pen and went straight to the main barricade holding back an estimated 500 people. The crowd surged forward and the barricade started to come down.

Police officers and Justin's personal security detail then surrounded him to usher him back inside. Police said a 47-year-old man standing in the doorway refused to step aside and had to be physically moved. The man was issued a summons for disorderly conduct and released. Police learned later that he was a member of the singer's security team.

The 17-year-old Canadian singer was not injured in the scuffle.

In fact, once back inside he seemed unfazed, and gave interviews to the press and posed for photographs with fans.

His publicist said: "This was a momentary, well-intentioned misunderstanding that was quickly resolved, and the event went very well."
